WILLIAM RUBIN, OF SOUTH OMAHA, NEBRASKA.

ROUND-CAN-FLOATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 743,567, dated November10, 1903.

Application filed January 30,1902. Serial No. 91,930. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM RUBIN, a citizen of the United States,residing at South Omaha, in the county of Douglas and State of Nebraska,have invented certain new and useful Improvements in Round-Can-FloatingMachines; and I do hereby declare the following to be a full, clear,andexact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a simple, inexpensive, andefficient mechanism for soldering the heads and bottoms of tin orsheet-metal cans to the bodies thereof.

It is a further object of my invention to provide means for adjustingthe said mechanism Figure 1 is a side elevation partly in sec tion. Fig.2 is a sectional elevation on the line X X of Fig. 1. Fig. 3 is aperspective view of the turn-over device at the end of the uppercan-track. Fig. 4. is adetail end view of part of the solder-feedingmechanism. Fig. 5 is a side view of the same, and Fig. 6 is a sectionalview of the lower solder-pot and the adjustable support for the sheavesfor the can-rotating cable. Fig. 7 represents an enlarged perspectiveview of the solder-pots and can-positioning guide with surrounding partsbroken away.

In the construction of the machine I employ a number of pairs ofsuitable standards 1 1 1 1, one of each pair on each side of themachine, which standards at their lower ends are secured upon suitablebase-blocks 2 and tightened hold the sections of pipe in position andkeep the standards properly spaced.

, Between the end pair of standards 1 and 1 are journaled in suitablebearings the shafts 7and 8, carrying the sprocket-wheels 9 and 10.

The bearing'boxes for shaft 8 are placed in slotted openings 11 instandards 1 and have adjusting-screws 12 for tightening an endless chain13, which passes around the sprockets 9 and 10.

The chain 13 is provided at regular inter vals with flat fingers 14, asshown in Figs. 1 and 2 and best shown in Fig. 3, secured on edge andprojectinglaterally beyond the side of the chain.

Except while passing around thesprockets 9 and 10 the chain 13 rests ona track formed of longitudinal angle-irons 15 15, which are supported bytransverse angle-irons 16 16,

around the curved track 18. After passing between the first pair ofstandards 1 this track is slightly inclined laterally, so that the cansare tipped over to bring the edge of the bottom downward and in thisposition are rolled through the solder-pot 19. This pot is supportedalongside of and below the chain-tracks 15 by the longitudinal bars 20,secured to the standards 1 l, andby transverse bars 21. While rollingthrough the solder-pot the cans are held down into thesolder and givenan additional rolling movement bya continuous cable 22, which is held inposition against the cans by small idler-sheaves 23, which areadjustably secured to standards 24, projecting upwardly from the bars20. In suitable bearings on the standards 1 1 are the shafts 25 and 26,carrying sheaves 27 and 28 for cable 22. The shaft 26 is driven throughthe medium of a pulley 29 thereon and a belt 30, connecting said pulleywith a second pulley 31 on a shaft 32, carrying a sprocket 33, connectedby a chain 34:, extending around a sprocket 35 on the shaft 7.

0n shaft 25 an arm 36 is pivoted, which carries on its opposite end asmall idler-sheave 37, which rests on the cable 22, keeping the sametaut.

The cans after rolling through the pot 19 pass over a guide 38, which isinclined laterally and further turns the can so that it rests on itsbottom. In this position the cans are slid along a track one side ofwhich is formed of one of the angle-irons 15 of the chain track and theother side of which consists of an angle-iron 39, as shown in Figs. 1and 3. The bottom of this can-track is formed of bars and 41 of roundedstrap-iron, which are secured to and supported by cross-pieces 42, whichin turn are secured to the chain track irons 15 and the side piece 39.The cross-pieces 42 have a number of holes 43 therein, so that the sidebar 39 and bar 41 may be set in varying positions thereon in order towiden the track to accommodate various sizes of cans.

At the end of the upper can-track, which is shown in Fig. 3, one of thebars 40 extends beyond the end of the other bar 41 and is slightlycurvedupward. When the cans are pushed off this track by the fingers 14 of thechain, they are supported and raised on one side by this bar 40, so thatthey are further turned a full quarter-way round and drop over ontheirsidesinto the flaring end of the chute 44 and roll down the same,following the line of travel of the chain 13 around the sprocket 9. Atthe lower end of this chute 44 the cans are'further slightly turned tocause the edges of their tops to roll through a second solder-pot 45, asshown in Figs. 2 and 6, the said tops being open heads of wellknownform. \tVhile passing through this pot the cans are rolled faster andheld in position as before bya cable 22, passing around adjustableidlers 23, mounted in standards 24*, sheaves 27 and 28*, andtightening-idler 37 of substantially the same construction andarrangement as the corresponding parts hereinbefore described, the cable22 passing around sheaves on shafts 32 and 32, as shown in Fig. 1. Afterpassing the pot the cans are further turned on their top ends by theinclined sides of a laterally-inclined guide 38 and in this positionslide along a track as before until reaching the sprocket. 10, where thetrack ends and the cans are dumped upon a conveyer or into suitablereceptacles.

It will be observed that the upper and lower solder-pots and guides areexact duplicates of each other, and I have illustrated the upper one inperspective, so that the construction of both may be fully comprehended.

The lower track from the solder-pot 45 to the end of said track iscovered, as shown in Fig. 1, by an elongated box 66, which has openings67 in its ends large enough to admit of the passage of the cans anddrivingchain and to permit of the insertion in said box of the trackstherefor. Inside the box 66 and below the can-trackis a pipe 68,whichhas on its upper side a number of small nipples or jets 69, which extendup close to the track. While the cans are passing along the track steamor water under pressure from any suitable source is forced into the pipe68 and through the jets 69. As the open ends or heads of the cans aredown ward, this steam or water will enter the cans, and also on thesteam or water striking the top of the box between the cans 66 it willdrop down on top of the cans, so that the cans will be washed thoroughlyinside and out in passing through the box 66. A drain-pipe 70 at one endof the said box serves to carry off the water or steam.

The construction of the solder-pots 19 and 45 is substantially similar,and the latter is shown in Fig. 6, which illustration will serve for thepot 19 also. It will be seen that the pot has a hollow space 46 belowfor the introduction of a suitable heating medium for keeping the soldermelted." Above this space is the pot proper for containing the solder,comprising a space 47, which extends into a projection 48 on the rearside of the pot. This space 47 is provided with a cover 49, on which thecans rest and which has a projecting rib 50 for holding the cans down,so that their edges will be sure to dip into the melted solder. Solderin the form of ribbon or wire is supplied to the pot 47 through a pipe51, as follows, as best shown in Fig. 2: On a shaft 32 is an eccentric52, which is connected by a twisted bar 53 to a link 54, which isadjustably secured to the pawl-arm 55 on shaft 56. This shaft extendslongitudinally of the machine and is supported in suitable bearingscarried by the standards 1 and 1". Adjacent to the pawl-arm 55 on shaft56 is a ratchet 57, with which a pawl 57*, pivoted to the arm 55,engages, so that the movement of the said eccentric will cause anintermittent rotation of the said shaft, the extent of which will becontrolled by the adjustment of link 54 on pawl-arm 55.

Centrally above the solder-pots 19 and 45 on the shaft 56 are wheels ordisks 58 58, having in their peripheral surface grooves or depressions59. (See Figs. 4 and 5.) WVithin these grooves run smaller disks 60' 60on arms 61 61", which are pivoted on the sections of the pipe 4 betweenthe standards. Springs 62 62 are attached to the arms and to loosecollars 63 63 on the shaft 56 and hold the disks 60 60 yieldingly incontact with the disks 58 58 A wire or ribbon of solder 51 is introducedbetween these disks 58 and 60, Figs. 1 and 2, and passes down the pipe51 to the solder-pot 45, being intermittently fed by the action of theratchetand eccentric mechanism, as described.

Pipe 51 serves to conduct solder-wire 51 to solder-pot 19, the wirebeing actuated by the is melted and fills the spaces 47 of the pots to asufficient depth. Power is applied to the pulley on shaft 7, and thevarious chains, belts, sprockets, sheaves, cables, &c., are driven, asdescribed. The cans to be soldered are placed in the feed-chute and rolldown-the same until they reach the track 18, when they are engaged bythe fingers 14 on the chain 13 and carried upward and rolled through thesolder-pot 19, so that one edge of the bottom of the can dips into thesolder contained therein. This rolling is assisted by the cable 22,which, it will be observed, travels in the same direction as the cansand at greater speed. On passing over the pan 38 the inclined sides ofthe same turn the cans over, so that they rest on their bottom ends andin this position are slid along the upper track until they reach the endthereof, when they drop into the chute it and roll down the same. Indropping into thischute the cans are further turned a quarter-way round,so that the edges of the top of the can which have not been soldered aretoward the front side of the machine. In this position they are rolledthrough the pct 45 and this remaining or top edge is soldered. Onpassing the guide 38 the cans are further turned a quarter-way round, sothat they reston their heads or open ends and in this position are slidalong the lowertrack and through box 66, being washed inside and outwhile therein, as described.

By means of the described construction I am enabled to solder both headsof the can and to thoroughly wash it inside and out Without thenecessity of handling the can during any part of both operations, andwhile I have specificallydesoribed the construction and operation of thevarious parts I desire it to be understood that I do not confine myselfto the exact constructions and arrangement, but hold that many minorchanges and variations therein might be made without departing from thespirit and scope of my invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
